TAKING MEASUREMENTS

DIRECT VOLTAGE MEASUREMENT

Connect red test lead to VΩ terminal, black test lead to COM terminal.

1. 

Set the dial function selector to DC voltage  „

2. 

„ and correct range corresponding to measured value. If you do 

not know range of DC voltage set the selector switch to maximum range and then reduce it gradually for the best 
measurement accuracy.
Switch on the multimeter with “Auto Power” button.

3. 

Connect or press test probes to measurement spots in the device or circuit. Measured voltage value and its polarity 

4. 

will be shown on the LCD display.

AC VOLTAGE RMS MEASUREMENT

Connect red test lead to VΩ terminal, black test lead to COM terminal.
